How do I install Weakspot?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Weakspot need an API key?

The publisher lists these environment variables: WEAKSPOT_PRIVATE_KEY, WEAKSPOT_MAX_USD, WEAKSPOT_URL, WEAKSPOT_RPC_URL.

What transport does Weakspot use?

Weakspot runs locally over stdio.

Weakspot

by dev.weakspot

Audit Solidity and Rust smart contracts from your editor. Pays per audit in USDC over x402.

The publisher's own command. Not a PlugMCP endpoint.

Local command

Credentials from the publisher

WEAKSPOT_PRIVATE_KEY — Private key of a funded Base wallet. This server SPENDS REAL USDC from it with no human in the loop — use a fresh wallet funded with only what you are willing to lose, never a personal or deployer key. Only weakspot_audit needs it; the pricing, status and wallet-status tools work without one.
WEAKSPOT_MAX_USD — Hard cap in USD on any single audit (default 4, the highest tier). Checked twice: against the tier price, and again against the amount the server actually quotes. An LLM decides when to call the paying tool, so this is the main spend control.
WEAKSPOT_URL — Base URL of the Weakspot deployment to use. Defaults to https://weakspot.dev; override to point at staging or a self-hosted instance.
WEAKSPOT_RPC_URL — Base RPC endpoint, used only to read the wallet's USDC balance in weakspot_wallet_status. Nothing else needs it.
